Why do we allow failure of leadership?

How is it going today currently in the military everyone says leadership is the most important thing. But yet we see the lower enlisted who just joined the military seem to think that they actually have more range of experience and seniors. Not just didn't see you as an officer's but specialist as well who may have been and as long as the NCO's and the officers as well. And that raises the question where his leadership actually gone? At the end of the day the thought pops into my head why don't we put the leadership back on the NCO's bring back hard leadership physical correction not just the counseling statement? The next thing is why would we take away from the leaderships why take the power from the NCOs they are supposed to be our direct leadership are NCO support channel yet it seems like more and more every one wants to just push away from the NCO's and try and leave themselves. We need to put the power back to the NCOs and allow them to do correction more than just a counseling statement or push for article 15 bring back the physical punishments the smoke sessions or possibly reduce the smoke sessions to a reasonable amount. I came in 2010, when I first joined just getting to the new unit as a brand new private I was smoked as being the new guy but I saw quickly that it wasn't just smoking it was being taught a lesson to learn respect of leadership of me. Which raises one thing for me. Coming from Military family background respect is everything to me, yet more and more I see total lack of respect from privates two PFC's who seem to think they're entitled to more respect than the senior people who are already above them who have been in longer and have more military experience and knowledge. Why have we left the Military get to this level of the moralizing and absolutely breaking people just because it seems like the right thing to do? Who says this is the perfect idea of a perfect way to lead people? Because the last time that I checked the Military itself is about respecting your leadership and following orders that you're given. Yet when it comes to certain things why do we have people who can't pass the pt test or height and weight or the tape test? Yet they are put in a leadership position? I don't think it's correct to do that, just how are you going to lead someone when you can't even do the tasks that you expect them to do? But everyone has their own ideals of leadership maybe we should start compiling ideas and improving leadership that we already have and take that as an example of what we should possibly fix. Toxic leadership is one of those horrible things that we have in the military right now, there's no way around it some leaders are toxic to unit and that has to be fixed if we are to have a military and has a high morale and good work ethic. I'd like to see other ideas on how we can make this happen and possibly this be a reality. And someone will get enough to push it up to the highest leadership possible in the military. That is all I just love to see the ideas that people would have to improve what we have already started.
